Answer:

The two equations are not equivalent and no property is used.

Step-by-step explanation:

54 - (30 - 8) ... (i)

(54 - 30) - 8 ... (ii)

Solving (i) and applying PEMDAS:

We open the brackets first;

54 - 30 + 8 = 54 + 8 - 30 = 32

Solving (ii) and applying PEMDAS:

We open the brackets first;

54 - 30 = 24

24 - 8 = 16

Troy’s canoe is 18 feet long. Ariel’s canoe is 5\6 the length of Troy’s canoe.

sukhopar [10]

5/6 = .83333333333333333333333333.... It goes on...
.833333333333333333 * 18 = 15
15 is your answer

Another way you could do it is 18/6 = 3
3+3+3+3+3 = 15

3 being 1/6th of 18 *Hope This Helps...*

A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the

trapecia [35]

1999 price = 11900
it depreciates 13%
$\frac{13}{100} \times 11900 = 1547$
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
$\frac{13}{100} \times 10353 = 1345.89$
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
$\frac{13}{100} \times 9007.11 = 1170.92$
year 2002 cost = 9007.11 - 1170.92 = 7836.19

An architect increases the radius of a circle window by 20 percent. By what percent

ale4655 [162]

Answer: 44%

Step-by-step explanation:

For a circle of radius R, the area is written as:

A = pi*R^2

Where pi = 3.14

If we increase the radius by 20%, the new radius will be:

R´ = R + 0.20*R = 1.20*R

The new area will be:

A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2

= 1.44*pi*R^2

And pi*R^2 = A, the original area, then_

A´ = 1.44*A = A + 0.44*A

This means that the percentage in which the area increased is:

0.44*100% = 44%
